# SOURCE
|
|
#
|
|
# .language: This program is written in awk as specified in the Single
|
|
# UNIX Specification from the X/Open Group (aka XPG4 UNIX, aka UNIX98).
|
|
# See http://www.opengroup.org/onlinepubs/7908799/xcu/awk.html for
|
|
# their man page.

# PURPOSE
|
|
#
|
|
# This program processes the output of cxref to find long
|
|
# identifiers.
|
|
#
|
|
# It outputs a list of functions that are used (ie those named appearing
|
|
# in the 3rd column: FUNCTION) whose names completely fill the column.
|
|
#
|
|
# A typical invocation might be:
|
|
#
|
|
# ./idlench.awk sos8cx/ci/*.o
|
|
#
|
|
# Not all awks are UNIX98 compliant; you need to find one that is.
|
|
# By default (if invoked as above) this script runs using /bin/nawk
|
|
# which on Solaris is a complant awk, but this isn't guaranteed for
|
|
# other systems.
|
|
#
|
|
# So the invocation might be something like:
|
|
#
|
|
# awk -f idlench.awk sos8cx/ci/*.o
|
|
#
|
|
# if there are problems with finding the right awk
|
|
|
|
# check for good awk
|
